What does "Internal server error" or "TX_MAX_SIZE_EXCEEDED" mean?

Short version: You are trying to send too many MRT at once. Send smaller amounts of MRT.

This error occurs when your wallet balance is made up of too many small transactions. It’s like having a bag full of change instead of larger bills. When you try and send a large amount of MRT that’s made up of too much change, it clogs the transaction. This is very common, especially if you’re pool mining.

The solution is to “clean” your wallet balance. Send smaller amounts of MRT to yourself until you’re able to aggregate all your transactions into a few larger ones. For example, if you tried to send 100 MRT and you get this error, try to send 50, if it still appears try 25, and so on. In general, you can “clean” your wallet every day by sending your entire wallet balance to yourself. This way you will be ready to send even bigger amounts of merit at once, which you will need to do if you want to sell MRT on the Market, for example. . Don’t be confused by the non-specific “Internal server error”, it’s usually indicative of the same “TX_MAX_SIZE_EXCEEDED” error described here.
